Abstract

This research work reported the development of a new disposable electrochemical chloramphenicol (CAP) sensor based on the use of a screen-printed electrode )SPE( modified with an iron oxide magnetic nanoparticles doping on graphene. The electrochemical and electrocatalytic characteristics of the modified SPE were recorded using cyclic voltammetry (CV) and differential pulse voltammetry )DPV(. The proposed sensor showed fast response to CAP and good sensitivity. The sensor had a detection range over the concentration ranges of 0.5 to 700 μM, with a detection limit of 95.4 nM (S/N=3).
